DESALINATION PLANT
Topic: Alternative tech.
In the latest development, Maharashtra announced the setting up of a desalination plant in Mumbai, becoming the fourth state in the country to experiment with the idea.
ABOUT
- A desalination plant turns salt water into water that is fit to drink.
- These plants are mostly set up in areas that have access to sea water.
TECH USED IN THIS PLANT
- The most commonly used technology for the process is reverse osmosis where external pressure is applied to push solvents from an area of high solute concentration to an area of low-solute concentration through a membrane.
- The microscopic pores in the membranes allow water molecules through but leave salt and most other impurities behind, releasing clean water from the other side.
- The states are using the technology are- Tamil Nadu, Gujarat, Andhra Pradesh.
